Embodiment
Below, with reference to the description of drawings embodiments of the present invention.
Fig. 1 is the figure of structure of the digital camera of the expression image processing apparatus that comprises one embodiment of the present invention.Digital camera shown in Figure 1 is by constituting with the lower part: CPU1; Camera lens 2; Imaging apparatus 3; AD converter section (being expressed as ADC in the drawings) 4; Memory 5; Image processing part 6; Jpeg coder/decoder 7; Storage card 8; Video encoder 9; Display monitor 10; With bus 11.
CPU1 carries out the control of the each several part of digital camera shown in Figure 1.For example, CPU1 carries out the work control of imaging apparatus 3 and the work control of reading control, ADC 4 and image processing part 6, jpeg coder/decoder 7, video encoder 9 of the picture signal that obtains by imaging apparatus 3 etc.
Have data image signal, comprise the various image processing of Filtering Processing as storage in image processing part 6 readout memories 5 of the function of Filtering Processing portion.Jpeg coder/decoder 7 utilizes the picture signal after method such as dct transform is handled image processing part 6 to encode when carrying out record images.After picture signal in this jpeg coder/decoder 7 behind the coding temporarily stores in the memory 5, record in the storage card 8 as the jpeg file that has added the header information of stipulating.In addition, when reproduced picture, the jpeg image signal of jpeg coder/decoder 7 playback records in storage card 8 utilizes methods such as inverse dct transform to decode.After in image processing part 6, decoded picture signal in this jpeg coder/decoder 7 being reduced into the given size that shows usefulness, temporarily store in the memory 5.Video encoder 9 is presented at the picture signal of storage in the memory 5 on the display monitor 10 as image.
Below, the image processing method of one embodiment of the present invention of having used image processing apparatus shown in Figure 1 is described.Filtering Processing at first is described.Fig. 2 is the concept map that is illustrated in when using 4 * 4 central interpolation filters that the view data that is made of rgb signal is carried out Filtering Processing in the image processing part 6.Herein, central authorities' interpolation filter is by a plurality of points in the filter (be 16 points) data of its central point to be carried out the filter of interpolation calculation at 4 * 4 o'clock, for example is used to remove the low-pass filtering treatment (LPF processings) of the radio-frequency component in the picture signal, the bandpass filtering treatment (BPF processing) of the characteristic frequency composition in the extraction picture signal etc.In addition, in Fig. 2, only show the Filtering Processing of a kind of signal component in the rgb signal, but other signal components are also carried out identical Filtering Processing.And not only rgb signal also carries out the explanation roughly the same with following explanation for the YC signal.
Under the situation of filter,, then can not carry out Filtering Processing, form by the shape shown in the label 101 of Fig. 2 so be used for rgb signal is carried out the filter of Filtering Processing if its inside does not comprise 16 points 4 * 4.The result who utilizes this filter 101 to carry out Filtering Processing carries out interpolation to the data of the central authorities in the filter 101.When for example having carried out Filtering Processing in the position of left upper end shown in Figure 2, point 102 shown in Figure 2 is by interpolation.By the All Ranges in the image is carried out this Filtering Processing, the point in the zone 103 has carried out interpolation by Filtering Processing.Shown in this zone 103 like that, in Filtering Processing, can't carry out interpolation a little to the institute in the filter, the peripheral part of image produce can not interpolation the zone.The size of this peripheral part is different with the signals sampling number of handling, the filter type of Filtering Processing use, the number of times of Filtering Processing etc., but in either case, the angle of visual field of the image after the Filtering Processing is all less than the angle of visual field of the image before the Filtering Processing.
For example under the situation of image 201 shown in Fig. 3 (a) having been carried out Filtering Processing (for example LPF handles), obtained deleting the image 201b behind the periphery image 201a of image 201.Herein, in the time of on the paper that image 201 and 201b is printed on identical size respectively, the angle of visual field of image 201b is compared with the angle of visual field of original image 201 and is changed, so the angle of visual field difference of two images after printing causes the possibility of inharmonious sense bigger to the user.
Thus, in this execution mode, utilize the method that illustrates with reference to Fig. 3 (b) to carry out Filtering Processing.Promptly, by the image before the Filtering Processing 201 is carried out Filtering Processing, obtained deleting the image 201b of periphery image 201a, but in this execution mode, after Filtering Processing, the image 202 that the periphery image 201a that generation is deleted by image 201b and filtered processing is synthesized into makes the angle of visual field of the image 201b after the Filtering Processing consistent with the angle of visual field of image 201.By generating this composograph 202, the angle of visual field of the image before the angle of visual field of the image after the Filtering Processing and the Filtering Processing is consistent, has reduced the inharmonious sense that brings to the user.
